Why is my dynamic paint image sequence coming out blank?
your subdivisions of your plane is far too big. So just make your plane much (!) smaller or subdivide it more (which i do not recommend if you do not want to crash your computer) - i just made your plane really tiny (after i rebought a new computer when i tried to subdivide it more...) and then  bake your images again and i got small red lines on the pngs. But i think your Shader setup is wrong too because i never saw red lines on the plane.
